2.) Also, more importantly, why does using 'centered' align, center and scale the panel perfectly horizontally but NOT vertically? It doesn't seem to scale down when the image's vertical size exceeds the Container's. It does recognize the top edge, but not the bottom. Scrolling is not turned on anywhere. Using 'Ext.Img' instead of 'Ext.Panel' behaves identically.

Please help. I have tried many different styling solutions, but can't seem to get it perfect. If anyone has a recommendation I'm all ears.
